pm2 startup error on Centos 6.3

[markkevans]

When running pm2 startup the following error is generated

pm2 startup
{ [Error: Command failed: /bin/sh: update-rc.d: command not found
] killed: false, code: 127, signal: null }

I guess there are 2 possible solutions

1. Check Platform OS and if not debian / ubuntu don't attempt to run update-rc.d
2. Check if update-rc.d script exists on the platform before attempting to run it

Any thoughts on the best way to solve this?

According to this stackoverflow post I think that the OS checking part is a bit fastidious and checking the update-rc.d script just take 1 line of code so I'd vote for the second way of doing this :).

I get the same error.

[Unitech]

Is there an update-rc.d tool like in CentOS ?

[markkevans]

Looks like chkconfig might be the centos version http://linuxcommand.org/man_pages/chkconfig8.html

[mani95lisa]

I want this too, please!

[purepear]

On CentOS 6.4 i had to add some config at the begining of the file...

# chkconfig: 2345 98 02

It's means booting at levels 2,3,4 and 5 and the other two numbers (98 02) are the priorities at boot and shutdown time i think

#!/bin/bash
# chkconfig: 2345 98 02
#
# description: PM2 next gen process manager for Node.js
# processname: pm2
#
### BEGIN INIT INFO
# Provides:          pm2
....

I think it's okay now, someone can tell me if it works on CentOS ?

To try the startup script :

$ npm install git://github.com/Unitech/pm2.git -g
$ pm2 startup centos

Thanks for feedback

[fakewaffle]

$ pm2 startup centos

Launching daemon
{ online: true, success: true, pid: 22761 }
⌬ PM2 You have to run this command as root
⌬ PM2 Execute the following command :
⌬ PM2 sudo env PATH=$PATH:/usr/bin pm2 startup

Is that what you expected?

[Unitech]

Yes, can you try now the command

sudo env PATH=$PATH:/usr/bin pm2 startup centos

I have a Linux AMI based on Redhat. Would you be able to get this script working for Redhat too?

[Unitech]

@ecoad give me more clues about how to start a process at startup on Redhat with V init scripts, thanks

[mani95lisa]

@Unitech I got the Empty error , please have a look. My server is CentOS release 6.4 (Final).

Thanks!

@mani95lisa
Your AMI probably uses chkconfig (like CentOS). From the looks of it, it probably succeeded. The init script would be in /etc/init.d/pm2-init.sh.

[HowtoGhost]

I have the same problem as @mani95lisa. Gives no feedback, does create the init script, but nothing starts on startup

[sudowork]

Can you copy paste the output of chkconfig --list?

[HowtoGhost]

https://gist.github.com/howtoinstallghost/8367225

also has the error from the pm2 error log

Thanks,
David

[mani95lisa]

I have to use forever to make it right, hope this problem could be resolved.

[Unitech]

At least pm2 has generated the init script.

Here is the line doing the chkconfig : https://github.com/Unitech/pm2/blob/master/lib/CLI.js#L204

If someone know the right command line to set a script at startup on CentOS, please share (:

[Unitech]

This worked for me on CentOS6.4

$ crontab -e

@reboot /root/.nvm/v0.11.9/bin/node /root/.nvm/v0.11.9/bin/pm2 resurrect
*/5 * * * * /root/.nvm/v0.11.9/bin/node /root/.nvm/v0.11.9/bin/pm2 dump

Just replace these values by what is written on the /etc/init.d/pm2-init.sh (node and pm2)

Tell me if it worked for you also

[aboutte]

@Unitech Your suggestion above works for me. I wanted to avoid using the cron to resurrect so I looked into why the init.d script wasnt working for me. I am running on the Amazon Linux AMI and the default init.d script was not starting my application. In the init.d script I removed the super function and all the calls to it and it started working for me.

Not sure if this is a bug with the init.d script but it worked for me.

[Unitech]

I've written a dedicated startup script for centos :

https://github.com/Unitech/pm2/blob/master/lib/scripts/pm2-init-centos.sh

It uses su instead of sudo and creates the lockfile to call the init script on shutdown.

Available on pm2 0.7.2

$ chkconfig --del pm2-init.sh
$ pm2 dump
$ npm install pm2@latest
$ pm2 kill ; pm2 resurrect
$ pm2 startup centos

[frankbecker]

I was able to run the startup command on an Oracle Linux machine, might have been Red Hat, even though I tried using redhat as a platform option.
pm2 startup centos

This worked beautifully, my pm2 processes restart when the server restarts.
